Problem statement

You have a requirement of sending notification to a specific slack channel using Laravel. You need to configure the incoming Slack WebHook on your Slack channel and then send notification from Laravel application.


Slack offers many ways for integration with external services. I’ll be using WebHooks to satisfy the requirement. This requires admin access to slack workspace.

Configure Slack Incoming WebHook

  1. Navigate to the Slack channel you want to send notifications to.
  2. Click channel details.
  3. Click Integrations.
  4. Click Add apps in apps card.
  5. Search WebHook.
  6. Click Install on Incoming WebHooks.
  7. Select add to slack.
  8. From dropdown select the channel.
  9. Click add Incoming WebHook Integration.

After that, On the Incoming WebHooks page, from the WebHook URL field, copy the WebHook URL, you should have a link something like:

Installing and configuring packages

Laravel offers official slack channel package. We can install it by composer.

composer require laravel/slack-notification-channel

Create a Laravel Notification.

php artisan make:notification SendSlackNotification

And then update the Notification as follows:


namespace  App\Notifications;
use  Illuminate\Bus\Queueable;
use  Illuminate\Contracts\Queue\ShouldQueue;
use  Illuminate\Notifications\Messages\SlackMessage;
use  Illuminate\Notifications\Notification;

class SendSlackNotification extends Notification {
	use  Queueable;
	public $level;
	public $message;

	* Create a new notification instance.
	* @return void
	* */
	public function __construct(string $level, string $message) 
		$this->level = $level;
		$this->message = $message;

	* Get the notification's delivery channels.  
	* @return array 
	* */ 
	public function via() {
		 return ['slack']; 

	* Get the Slack representation of the notification. 
	* * * @return \Illuminate\Notifications\Messages\SlackMessage 
	* */  
	public function toSlack() { 
		$slackMessage = new  SlackMessage();
		$slackMessage->level = $this->level;
		$slackMessage->content = $this->message; 

		return  $slackMessage; 

Sending notification

Sending notifications on-demand. Laravel provides an on-demand notification facade.


use Illuminate\Support\Facades\Notification;

$slackWebhookUrl = '';
$message = 'Test message';

Notification::route('slack', $slackWebhookUrl)
	->notify(new  SendSlackNotification('success', $message));


Congratulations 🎉, you can use the Notification route to trigger dynamic notifications from anywhere in the application. There are a lot of improvements can be made added. My goal was to get you started quickly.
